First graph of isotherms, showing mean temperature around the world by latitude and longitude. Recognizing that temperature depends more on latitude and altitude, a subscripted graph shows the direct relation of temperature on these two variables

Color-coded bivariate matrix to represent two intervally measured variables in a single map (Urban Atlas series)[but see Georg von Mayr in 1874 cite[Fig. XIX]{vonMayr:1874} for first use]
